Error message:

IdeaLoggingEvent[message=null, throwable=java.lang.IllegalStateException: 'runBlockingCancellable' is forbidden in the Write Action because it may start a long-running computation. This can cause UI freezes.
Consider running this 'runBlockingCancellable' under a read action outside your Write Action'

Start in Profile.java at line 198, where addConnectionToDotEnv is called, and review the callers shown in the stack trace: addConnection and createOrUpdateConnection. Check the connection flow that triggers the write action and ensure the runBlockingCancellable call is no longer made there; done means the reported IllegalStateException no longer occurs.
